To all whom it may concern:

Be it known that I, EDWIN A. MARTIN, of Thornville,in the county ofPerry and in the State of Ohio, have invented certain new and usefulImprovements in Grain-Sacking Scales and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementofa grain-sacking scale, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and now proceed to describe its construction andoperation, referring to the annexed drawing, in which Figure l is a sideelevation, gitudinal vertical section, of

A represents the box to W ing parts are attached. opening, 13, at thetop, grain is poured in, and box divides into two inc with openings at aat the end of the box.

The mechanisms attached to the box are precisely the sam and hence adescription of for both.

There is, however, oted in the sides of mouth B, which from side toside, alternately nals of thi and Fig. 2 a lonmy invention. hich all thework-- i This box has an through which the below the same the linedpassages, G G, bottom-one at each the ends of e at both ends, one willanswer a valve or gate, D, pivthe box A, below the valve is to be thrownover to direct the flow of grain into the passages O G. Thejours valveproject through the sides of the box, and upon each one is secured alever, D, having both ends pointed, as shown.

At the end of the box A is secured a frame, E, and in the same uponsuitable knife-edges is hung a cross-bar, G.

From the center of this crossforward a beam, G end, and a hook, I, suone end of the bar G backward along on this scale-beami bar extendshaving poise H on its spended from it. From G extends a scale-beam, theside of the box, and s an adjustable Weight,
